Importance of Agricultural Entomology



Controlling insects and other arthropods has become an increasingly complex issue over the past two decades. Minimizing losses due to insect pests and insect vectors of important plant, animal, and human diseases remains an essential component of the programs in the Office of Agricultural Entomology. Nonetheless, the deleterious effects associated with the use of chemicals, such as development of insect resistance to insecticides, poisonous residues on foodstuffs, human illnesses associated with pesticide applications, contamination of soil and water, and diminution of biotic diversity must be reduced or eliminated. As a result, considerable emphasis has been placed on tactics other than chemical controls, including biological, cultural, and genetic methods and the deployment of varieties resistant to pests. A re-evaluation of the economic thresholds of insect pests and vectors and the concurrent development of models capable of generating management strategies are a direct result of the need to reduce our reliance on chemical controls. The concept of integrated pest management (IPM), introduced in the late 1950s and more widely practiced during the 1970s and 1980s, remains the viable and preferable approach to reducing constraints caused by pests. In addition, IPM is currently held as the model upon which the concept of sustainable agriculture can be structured.

Name

Use

1

Insect trap

Insect traps are used to monitor or directly reduce populations of insects or other arthropods. They typically use food, visual lures, chemical attractants and pheromones as bait and are installed so that they do not injure other animals or humans or result in residues in foods or feeds.

2

Killing jar

 

killing jar is a device used by entomologists to kill captured insects quickly and with minimum damage.[1] The jar, typically glass, must be hermetically sealable and one design has a thin layer of hardened plaster of paris on the bottom to absorb the killing agent. The killing agent will then slowly evaporate, allowing the jar to be used many times before needing to refresh the jar.

3

Butterfly net

butterfly net (sometimes called an aerial insect net) is one of several kinds of nets used to collect insects. The entire bag of the net is generally constructed from a lightweight mesh to minimize damage to delicate butterfly wings. Other types of nets used in insect collecting include beat nets, aquatic nets, and sweep nets. Nets for catching different insects have different mesh sizes. Aquatic nets usually have bigger, more 'open' mesh. Catching small aquatic creatures usually requires an insect net. The mesh is smaller and can capture more.

4

Pheromone trap

pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure, as the red rubber septa in the picture, is encased in a conventional trap such as a bottle trap, Delta trap, water-pan trap, or funnel trap.

5

Bee Hive

 

Honeybees can live in hollow trees, wall voids in buildings, attics, or any other protected place. Several types of hives have been designed to manage honeybees. Old-fashioned hives were simple devices, such as plain boxes, short sections of hollow logs called gums, or straw baskets called skeps. These hive styles have many disadvantages and are rarely used now. Combs in them were usually irregular and braced together with bur comb. Individual combs could not be removed from the hive without damaging other pieces or even injuring or killing the queen. It was also difficult to inspect the hives for diseases and other problems.
